What is Water?


The cells of all living organisms are made up of water. The human body is composed of 60% to 70% of water, this water circulates continuously and is essential for all life processes. In a temperate climate, an average person should consume more than 2 liters of water a day. In fact, the body eliminates more than a liter of water every day, through urine, sweat, faeces and during breathing.

To keep the body healthy, these losses must be compensated by an equivalent water consumption. It is therefore very important that the water ingested by the individual is of excellent quality.

The absorption capacity of coal has been known for some time, in the Renaissance period to improve the clarity and taste of the water was made to flow on a bed of coals.

The gas masks of the First World War were equipped with cartridges made of activated carbon, In cases of ingestion poisoning, in addition to the classic gastric lavage, the use of activated carbon is used. Its power ceases when the external structure of the coal is saturated, as it is no longer able to adsorb.

With modern techniques, different types of carbon filters were defined as “active”.

The use of activated charcoal for applications on drinking water generally takes place in three forms. Granular (GAC), in powder (Everpure®), Extruded and added with ion-exchange resins and silver ions to eliminate bacterial proliferation

Microfiltration is a filtration technique that guarantees water purity and usually occurs through the use of special filters, which improve its organoleptic characteristics, without altering the values of mineral salts contained in water.

The microfiltration system makes the water pleasant to taste and retains the impurities given by the old pipes, completely eliminating chlorine, pesticides and substances in suspension without changing their organoleptic characteristics, making the water excellent for drinking and cooking directly at home.

Many people to solve the problem related to the bad taste of tap water, prefer to spend money and effort in buying bottled water or adopting temporary solutions. In this way, however, the problem is only partially solved, as for cooking and preparing coffee they continue to use tap water and therefore usually ingest unwanted substances contained in it.

Water microfiltration is an ecological and safe system. 

Reverse Osmosis

Reverse osmosis is a process used to purify the water from impurities of various kinds. This technique exploits the potential of a semipermeable membrane, for example a cellulosic film, which can be traversed by solvent (in our case water) but not by solutes (impurities). In natural conditions, if two vessels are separated from this membrane, the solvent passes from the area where it is most concentrated to that in which it is present in lower concentrations.

To bring us back to our example, water passes from the container where it is purer (eg distilled water) to that in which it has a lower degree of purity (eg salt water). This passage stops when the two containers reach the same ratio between water and impurities.

In reverse osmosis, a pressure is applied to the container where the water is less pure to overcome its natural tendency to enter this compartment. In this way there is an inversion of the natural osmotic flow and, to return to the previous example, the passage of water in the sense “concentrated solution (more impurities) → diluted solution (less impurities)”.
